Moving my camera around an constructing object
I don't know much about Python if that's what you're asking, but if you aren't and want to zoom the camera out through your animation, try moving the timeline cursor to the first frame, keying "I" and choosing LocRotScale. Then move to the end of your animation and repeat.

If you want to rotate the camera around the object, follow these instructions: How can I animate the camera in a perfect circular rotation around a fixed position?

I'm not sure if they work together, but they might. If they don't, look into camera focal length.

Hope this helps and happy Blending!
